Abstract: An automated oyster maturation system including a containment assembly rotatably disposed within a housing. The containment assembly includes a spiral construction that includes compartments that are in communication with one another, walls that define the compartments, and ramps. Openings disposed in the walls and ramps increase in size from the outer diameter to the inner diameter of the spiral construction so that, with every complete rotation of the containment assembly, every oyster will tumble further into the spiral construction and ascend from its original compartment into the adjacent inner compartment where opening size is larger than in the original compartment such that only oysters which have grown sufficiently can remain in the adjacent inner compartment while oysters that have not grown sufficiently yet will fall through the openings of the adjacent inner compartment into the original compartment.

Abstract: A cryogen-blanching technique involves brief exposure of an oyster shell to a cryogen. The cryo-blanching weakens the oyster's muscles that close the bivalve tightly shut, but preserves the natural condition of the bulk of the oyster meat. The weakening of the oyster's holding muscles allows shucking the oyster meat in its fresh or natural state without damage or shell fragments.

Abstract: An apparatus for washing and rinsing bivalves and other mollusks. The bivalves are placed in a hemisphere-shaped strainer and another hemisphere-shaped strainer is attached thereto to form a spherical strainer cage. The spherical strainer cage is mounted on a stand so that it may rotate freely about its axis. The cage rotates on the stand and a rinsing liquid is applied to remove debris from the bivalves contained in the cage.

Abstract: A method of gutting a cephalopod, such as squid, the cephalopod having an outer mantle containing internal organs, and the method comprising retaining the outer mantle at a fixed distance from a central axis while rotating the mantle about the said axis whereby the internal organs are subjected to a centrifugal force sufficient to eject the organs outwardly through an open end of the mantle.

Abstract: A method of processing abalone is disclosed. The first step involves placing live abalone in a tank of water where they are given an opportunity to de-stress. Thereafter the salinity of the water is decreased to about 2.5%. This has the effect of additional weight being taken up on the musculature of the abalone. Thereafter the abalone are anaesthetised in the tank to minimise any muscular activity during subsequent processing. The abalone are then taken out of the tank and shucked to detach the meat or musculature from the shell and gut exposing the three main blood vessels of the abalone. These blood vessels are then blocked by inserting a blocking material into the open end of the vessel where it forms a plug. This resists the flow of body fluid including blood out of the abalone and assists in retaining the weight of the meat. After the meat has been cleaned a liquid is injected into the meat typically by a multipoint injector.

Abstract: An apparatus for mechanically rinsing and scraping bi-valve mollusks and the like. The mollusks are placed into a perforated drum that is rotated by a motor, the drum having a plurality of agitation protrusions for churning, lifting and dropping the mollusks so they become frictionally engaged with one another and the plurality of abrasive elements contained therein thereby effectively scraping off any barnacles or other like debris. Jet streams of water are emitted to shower the mollusks during operation and a housing assembly that maintains the perforated drum therein also forms a basin that retains the effluence and creates an agitating, churning bath to facilitate cleaning. The front panel of the housing assembly is hinged to a bottom plate thereof and has two perpendicular side panels extending therefrom to form a chute for unloading the mollusks in an orderly manner into a bucket or other like container.

Abstract: The invention relates to a process for eliminating pathogenic organisms and other bacteria from raw food products, such as raw shellfish, whereby the molluscan shellfish is exposed to hydrostatic pressure of relatively high value, for example between 20,000 p.s.i. to 150,000 p.s.i. for 1-15 minutes. The process is conducted at minimal elevated temperatures, in the range of above ambient temperature to 150° F., leaving the raw shellfish substantially unaffected, in its desired raw state, such that the pathogenic organisms are destroyed, while sensory characteristics of the raw shellfish remain high. The same process can be used for shucking bivalve mollusks without any mechanical force, with the pressure ranging from 10,000 p.s.i. to 100,000 p.s.i. Taste of raw seafood is enhanced by adding flavor enhancing agents to the pressure vessel before application of pressure.

Abstract: The invention relates to a process for eliminating pathogenic organisms from raw food products, such as raw shellfish, whereby the molluscan shellfish is exposed to hydrostatic pressure of relatively high value, for example between 20,000 p.s.i. to 50,000 p.s.i. for 1-15 minutes. The process is conducted at ambient temperatures, leaving the raw shellfish substantially unaffected, in its desired raw state, such that the pathogenic organisms are destroyed, while sensory characteristics of the raw shellfish remain high. The same process can be used for shucking oysters without any mechanical force. A high pressure processor for elimination of bacteria in raw food products is disclosed.

Abstract: Apparatus for determining the position of a bivalve shellfish (10), particularly a scallop, which is to be processed to recover an edible portion. A shell shape complement (30) has at least a partially complementary shape such as a concavity or recess to fit with at least a part of the shape or profile of the shellfish (10) such as the projecting part (18) at the hinge region (11). Moving means (40) rotates the shellfish relative to the shell shape complement (30) while the shellfish is maintained in contact with the shell shape complement (30) by biasing means operative to bias the shell shape complement (30) against the circumference (15) of the shellfish as the shellfish is rotated by the moving means (40) until a fit of the shellfish (10) with the complement is achieved. A sensor (45) is located within the concavity to sense and signal the achievement of the fit.

Abstract: An apparatus for cleaning the shells of crabs and other crustacean and shellfish for removal of barnacles and other encrusted debris. A conveyor carries the shells through a cleaning station. The cleaning station features a rotating flail, having chains or other like flexible members for impacting against the shells with hard, smooth members for selectively shattering the barnacle shells while permitting the relatively softer crustacean shells to remain intact.

Abstract: An automated crustacean processing apparatus provides a scrubbing of crustacean leg portions at high speed and volume and additionally maximizes the amount of leg processable. A cutting arrangement is provided to sever the legs from the body portions with minimum wastage of usable leg material. Asymmetric scrubbing of the upper and lower leg surfaces means that the upper surfaces, which are less debris-laden and feature a commercially significant layer of red colouring receive a less vigorous scrubbing then the leg undersides, which are more debris-laden and do not feature a red layer.

Abstract: A method of processing bivalve molluscs comprises filling a basket-like container (11) with the bivalve molluscs and vibrating the bivalve molluscs within the container (11), thereby inducing them to close tightly under stress and compacting them together. A lid (12) is closed to maintain the compact configuration of the bivalve molluscs, which are cooked by immersing the container into boiling seawater, before being removed and plunged into chilled water to halt the cooking process. The bivalve molluscs are then blast frozen. Because the shells of the bivalve molluscs are tightly closed and better compaction is achieved by vibrating the bivalve molluscs than by compressing them into the container (11), the shells are unable to open and the internal juices are retained within the shells throughout the cooking, chilling and freezing steps, thereby resulting in processed bivalve molluscs having greatly improved organoleptic qualities upon thawing.
